Foreground Analysis Using Cross-Correlations of External Templates on the 7-year WMAP data
Tuhin Ghosh, A. J. Banday, Tess Jaffe +4
WMAP data when combined with ancillary data on free-free, synchrotron and dust allow an improved understanding of the spectrum of emission from each of these components. Here we ex…
Planck Intermediate Results. I. Further validation of new Planck clusters with XMM-Newton
The Planck Collaboration, N. Aghanim, M. Arnaud +182
We present further results from the ongoing XMM-Newton validation follow-up of Planck cluster candidates, detailing X-ray observations of eleven candidates detected at a signal-to-…
Template fitting of WMAP 7-year data: anomalous dust or flattening synchrotron emission?
M. W. Peel, C. Dickinson, R. D. Davies +3
Anomalous microwave emission at 20-40 GHz has been detected across our Galactic sky. It is highly correlated with thermal dust emission and hence it is thought to be due to spinnin…
Constraining the topology of the Universe using the polarised CMB maps
P. Bielewicz, A. J. Banday, K. M. Gorski
We study the possibility for constraining the topology of the Universe by means of the matched circles statistic applied to polarised cosmic microwave background (CMB) anisotropy m…
Analysis of WMAP 7-year Temperature Data: Astrophysics of the Galactic Haze
Davide Pietrobon, Krzysztof M. Gorski, James Bartlett +10
We analyse WMAP 7-year temperature data, jointly modeling the cosmic microwave background (CMB) and Galactic foreground emission. We use the Commander code based on Gibbs sampling.…
Search for non-Gaussianities in the WMAP data with the Scaling Index Method
G. Rossmanith, H. Modest, C. Raeth +3
In the recent years, non-Gaussianity and statistical isotropy of the Cosmic Microwave Background (CMB) was investigated with various statistical measures, first and foremost by mea…
